Description

Technical Field

[0001] The utility model relates to a polishing machine, in particular to a gear type grinding and polishing machine, belonging to the technical field of polishing machines. Background Art

[0002] A grinding and polishing machine is a grinder that uses a grinding tool coated with or embedded with abrasives to grind the surface of a workpiece. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece. When in use, the object to be polished and the grinding material are placed in the grinding tank, and the grinding tank is driven to rotate by the turntable. Under the action of centrifugal force, the object to be polished and the grinding material collide with each other, which can not only grind the workpiece flat, but also polish the surface of the workpiece to achieve the purpose of grinding and polishing.

[0003] An ultra-high-speed centrifugal pressure grinding and polishing machine disclosed in the Chinese patent application disclosure specification CN219337328U changes the traditional self-locking worm gear reducer into a hard-tooth surface reducer and hollows out the grinding barrel to reduce its weight, thereby greatly reducing its weight and achieving high-speed rotation of the barrel. However, this solution lacks a limit on the grinding material. For the grinding and polishing process, blindly increasing the rotation speed of the barrel will cause the grinding material to generate greater centrifugal force inside the barrel as the barrel rotates. When the centrifugal force is too large, the grinding material and the object to be ground will be pressed against the barrel wall surface by the centrifugal force, which not only affects the grinding work, but also reduces the grinding efficiency due to the lack of speed difference between the grinding material and the object to be ground. For common grinding and polishing machines, in order to ensure the stability of the raw materials during grinding, the feed port usually adopts a threaded mounting baffle, which is not convenient for loading and unloading.

[0027] Please refer to Figure 1 , Figure 3 and Figure 4The guide block 9 is located below the arc guide plate 7. The guide block 9 is slidably connected to the drum 3. The arc guide plate 7 does not contact the drum 3, which is beneficial to the stability of the guide block 9 and the arc guide plate 7, thereby maintaining the overall stability. A drive motor 10 is installed on the right side of the side plate 4. A drive gear 11 is installed at the output end of the drive motor 10. A gear ring 12 is fixed to the outer surface of the rotating sleeve 6. The drive gear 11 is meshed with the gear ring 12, which is beneficial to the stability of the drive gear 11. The drum 3 can be driven to rotate stably through the output end of the drive motor 10.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 A box door 13 is hinged on the side of the side panel 4 on the right side, and two auxiliary blocks 14 are fixed to the right side of the box door 13. A plug rod 15 is arranged between the two auxiliary blocks 14. A plug block 16 is fixed to the right end of the rotating drum 3. The plug rod 15 is plugged into the plug block 16, which is beneficial to the stability of the plug rod 15 and further helps maintain the stability of the box door 13. A reset spring 17 is installed on the upper surface of the plug rod 15, and the other end of the reset spring 17 is connected to the auxiliary block 14 located above, which is beneficial to the stability of the reset spring 17. The elastic force of the reset spring 17 pushes the plug rod 15 to reset and plug it into the plug block 16.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 Two track plates 18 are fixed to the outer surface of the rotating drum 3, and a plurality of supports 19 are installed on the upper surface of the bottom plate 1.
